Answer:
Step-by-step explanation:
The given equation is 9 = 3 × (-12). To solve this two-step equation, we need to isolate the variable on one side of the equation. We can do this by first dividing both sides of the equation by 3:
9/3=3×(−12)/3
This simplifies to:
3=−12
The equation is 9 = 3x - 12.
First, let's add 12 to both sides of the equation to isolate the term with the variable on one side.
9 + 12 = 3x - 12 + 12
